Title: Method of calculating radiation
Inventor: OKAZAKI HIROFUMI
IPC: G06F17/50
Filed: 2003-03-21
Abstract: The present invention proposes a method for calculating radiation energy exchanges rapidly and accurately. Near a calculation cell where energy exchange occurs, a small (level 0) cell is used and at a location remote from the calculation cell P, a large (level n) cell formed by combining plural small cells is used. Furthermore, the largest calculation cell which comes into a field of view angle .DELTA. .OMEGA. covered by a ray is selected. As a result, the accuracy of the radiation eneregy exchange calculation is enhanced, the calculation time is shortened and the amount of memory necessary for the calculation can be reduced.

Patent CA-2429930-A1 (CA)
Title: Sequentially cross-linked polyethylene
Inventor: WANG AIGUO
IPC: A61L27/16
Filed: 2003-05-27
Abstract: A method of producing an improved polyethylene, especially an ultra-high molecular weight polyethylene utilizes a sequential irradiation and annealing process to form a highly cross-linked polyethylene material. The use of sequential irradiation followed by sequential annealing after each irradiation allows each dose of irradiation in the series of doses to be relatively low while achieving a total dose which is sufficiently high to cross-link the material. The process may either be applied to a preformed material such as a rod or bar or sheet made from polyethylene resin or may be applied to a finished polyethylene part. If applied to a finished polyethylene part, the irradiation and annealing must be accomplished with the polyethylene material not in contact with oxygen at a concentration greater than 1% oxygen volume by volume. When applied to a preform, such as a rod, the annealing of the bulk polymer part of the rod from which the finished part is made must take place on the rod before the implant is machined therefrom and exposed to oxygen.

Title: Method and means for detecting gluten-induced diseases
Inventor: KORPONAY-SZABO ILMA
IPC: G01N33/564
Filed: 2002-04-24
Abstract: The invention is directed to a method of detecting gluten-induced diseases such as e.g. celiac disease and dermatitis herpetiformis. Said diseases are indicated by the presence of autoantibodies against tissue transglutaminase tTG in the blood. The test is carried out on a whole blood sample using tTG  liberated from the red blood cells of the blood sample as an autoantigen. The liberated autoantigens react with the autoantibodies in the sample and form antigen-antibody complexes, which are detected. The presence of such complexes indicates the disease. The invention is also directed to the use of the autoantigen in a test and to a test-kit.

Abstract: A ball dropping assembly (350) for dropping one or more objects, such as spherical balls, (5,5',5") into a wellbore (7). The assembly comprises a seat (330) for retaining a ball before it is released. The assembly may also comprise a ball feeding channel (380) for feeding additional balls onto the seat. A ball retaining lever (40) is provided to selectively receive and retain balls onto the seat (330), and then to release the balls individually into the wellbore (6). In one embodiment, the assembly is attached to a side bore (4) in fluid communication with a main bore in a cementing head (105).  The ball-retaining lever (40) rotates into the bore (6) when releasing a ball (5'). When a plug (8) is released into the bore from a cementing head (105), the plug (8) will trip the lever (40), causing the ball-retaining lever to rotate back towards the ball-retained position. Thus, the ball dropping assembly also serves as a plug release indicator.
